DRAFT-TUBE FOR DRAWING SODA-WATER, 80C.

SPECIFICATION formingpart of Letters Patent No. 229,304, dated June 29, 1880.

Application led April D, 1880. (No model.)

4large or iiat stream is substituted for such sharp stream, in order that the contents ofthe drinking-vessel, when filled, shall consist of the proper quantity of solidliquid; and the invention consists in so combining with the draft-tube an inverted condensing vessel or bottle that a sharp stream may be delivered.

from such tube directlyinto the drinking-vessel until the sirup therein is sufficiently cut, whereupon such direct sharp stream may be discontinued, and a stream delivered against the interior of such condensing-vessel, which, breaking thereon', will be condensed, and will flow through the inverted passage in the lowerV end of such condensing-vessel, falling thence into the drinkin g-vessel as a solid stream.

It also consists in the means and method of combining the inverted condensingvessel and the draft-tube, and in the constituent devices of such tube itself.

Figure 1 isa longitudinal vertical section taken through the axis of the draft-tube and condensing-vessel. Fig. 2 is a side elevation of the condensing-vessel and of that portion of the draft-tube which extends outward beyond the coupling-nut. Fig. 3 is a plan view of the central portion of the draft-tube, and showing the actuatinglever, the stop-pin, and the stops with which it comes in contact. Fig. 4 is an axial horizontal section of the central portion of the tube, showing the packing, the

passages, the side cock, and the coupling-nut, all in section. Fig. 5 is a detached plan view of the` meeting ends ofthe two sections of the tube, and also showing, in plan, the packing employed between said sections, as also the interposed disk. Fig. 6is a horizontal section taken on line A B, Fig. 1.

In the said views, a represents the body of the tube, having the usual threaded shank b, Fig. 1, by which it is secured in the vertical slab' or fountain front c in the well-known manner.

d is the axial passage by which the liquid is introduced into the tube, and which extends to near the outer or front vend of body a, as shown in Figs. 1, 4, and with which the intermediate minor passages, 5 6, communicate, as shown in Fig. 4. l

An extension or outer tubular section, e, is

`coupled to section a, by coupling-nutf, which is threaded upon part a, and engages shoulder 15 of a sleeve, g, Fig. 5, which is arranged upon part e, and which, at its inner face, engages the shoulder 14' of part @,FigA, thereby securing parts a and e in axial coincidence, as shown in Figs. 1 and 4. The outer extremity of part e is inserted through an aperture in the sideof the condensing-vessel Z, and terminates in a curved nozzle, 16, as shown.

To secure vessel Z upon part e, a shouldered sleeve, k, extends out through the aperture in the side of Z, and upon it is threaded a collar,

j, into which is concentrically recessed the setcollar l,which is adjustable upon and secured to part e by a set-screw, a packing', a, being interposed between t' and j, as shown in Fig. 1, to prevent escape of the liquid from l, an elastic packing being also interposed between the wall of vessel l and the sleeve .7a and collar j.

` The inverted neck of vessel l is inserted in a ring, fm, which is formed upon rod n, which latter is inserted in stud 0 and locked by setscrew s, said stud o being inserted in tube p of part a, and secured by screw t, Fig. 6 5 and as rod a may be lineally adjusted to bring the mouth 19 of vessel l centrally beneath nozzle 16, while stud o is vertically adjustable, and set-collar t' can be adjusted against packing u, by these means vessel lean be accurately adjusted and secured upon tube e and relatively to nozzle 16, while' the tube will be free to revolve upon its axis, as will be presently described. u,

ln Fig. 4 is shown a plug, 22, fitted in body a and secured in position by the packing-nut IOO to actuate it. A transverse passage through this plug is shown in said Fig. 4 as coincident with a passage, 6, which leads from axial passage d to the annular recess in the outer end of et, while a parallel passage, 5, also leading from,

passage d to said recess, is not penetrated by said plug, and by rotating plug 22 more or less the passage 6, will be thereby in the same degree reduced in the volume of its effective delivery. In the bottom ot'said recess is seated the elastic packing C, which is formed with a disk-like body, 1, a projection,2, and two passages, 3 4. Said projection is seated in the longitudinal slot x, Fi g. 5, which is cut through the wall of part c, which incloses said annular recess; and when said packing is so seated it is held from rotary displacement by said projection, and said passages 3 4 are coincident with passages 5 6, as shown in Fig. 4.

Upon the inner face or end of part e is formed or secured a central pin, 11, and a short tube, l0, the passage in which is a prolongation of the axial passage 9 in part c, and said` tube is arranged at the samel distance froni the axisoi' e as are the passages 5 6i'rom the axis of u.

An elastic packing, 12, Figs. 1, 4, 5, is formed with an axial passage to receive the central pin,y 11, and with a hole, 18, to receive tube 10, anda disk, 13,formed of hard rubber, metal, or other suitable material,is perforated at the center, and with a side passage, 17, in the same manner as is packing 12, to receive said pin 11 and tube 10.

A shox-t stud or stop-pin, v, is secured in extension c, so as to be brought in contact with the stops u, formedin sleeveg,F igs.2, 3, which are atone hundred and eighty degrees from each other, to allow a halrevolution of'part e in either direction before arrested by said pin, said sleeve beingI secured from rotation by a stud, i ,formed upon its shoulder 15, which enters and is locked by slot in part c, as shown in Figs. 1, 5.

For the purpose of rotatingpart e an arm, h, is rigidly secured thereto and in the same plane as thev pin 0) so that when said pin is in contact with either of shoulders w the arm 7L will be in a horizontal position, and when in such position the passage in tube 10 of part c will be coincident with one or theother of passages 5 6 in part a; and as the passages in packing C are always coincident with passages 5 6,7 and as the packing 12 and disk 13 are, by their contact with tube 10 and pin 11, always revolved coincidently with parte, therefore when the passage in part e is coincident with one of thel passages 5 6, there will be al continuation thereof through the said two packings and said disk.

When lever his in a vertical position the axial passage in e is intermediate between passages 5 6, and the face ot' e then constitutes the valve;A therefore the part c, while serving as a portion of the draft-tube, is alsov the valve and valve spindle or stem, while arm 71. supplies the place of a hand-wheel usually attached to such spindle.

When a glass of soda is to be drawn, and a sharp stream being firsty required, the-lever h is turned to the position shown in Fig. 3, which will turn nozzle 16 downward, as shown in Fig. 1, and will also bring the axial passage in c coincident with passage 6 in a, whereby a sharp stream will bedelivered directly into the tumbler. Said nozzle 16 being arranged, as described, in the axis of vessel Z, such stream will pass through mouth 19 without contact therewith, and without being broken, and such stream will, by the adjustment of plug 2, as before described, be graduated in its force as the pressure in the supply-fountain may render necessary.

When said sharp stream has suiilciently cut the sirup, lever h will be reversed to the position shown in Fig. 4, thereby turning nozzle 16 upward, as shown in Fig. 2, and bringing dense the aerated liquid discharged within it,

and is clean and incorrodible. I claim as my invention- 1.. In a draft-tube, the combination of the inverted condensing-vessel and a conduit-tube 'constructed and arranged to deliver a stream within said condensing-vessel in an upward or downward direction, as desired, whereby a sharp stream` may be rst delivered direct into the drinking-vessel, when a stream may be. delivered again st the interior of the condensingvessel, and be thence delivered into the drinking-vessel, substantially asy specified.
